Integrated Processing Features

The XTi2 Series amplifiers include a number of integrated processing features which appear as icons on the
front panel LCD screen. They are described below:
NOTE: System Architect Software is required to have full control over all Integrated Processing
Features which can be downloaded from the following URL – http://hiqnet.harmanpro.com/.
When controlling more than one XTi2 at a time you will need USB Hub. We recommend using a
Powered USB Hub.
Input Mode
• Stereo - In this mode, Channel 1 input goes to Channel 1 output and Channel 2 input goes to Channel 2
output. This is the mode the amplifier is configured for from the factory.
• SUM (CH1 + CH2) – In this mode, the Channel 1 input signal and Channel 2 input signal are summed and
fed to both output channels. This provides a 6 dB level boost.
• Input Y – In this mode, the Channel 1 input signal is sent to the Channel 1 and Channel 2 output. The channel
2 input signal is ignored.
Output Mode
• Stereo – In this mode, the amplifier sends Channel 1 input signal to the Channel 1 output and the Channel 2
input signal to the Channel 2 output.
• Bridge-Mono – In this mode, the power of both amplifier channels are delivered into a single 8 or 4 ohm load.
Subharmonic Synth
The Subharmonic Synth feature takes the low frequencies and "synthesizes" or creates new frequencies that are
one octave lower. The two signals are then summed together. Also new, are two user adjustable parametric EQ
filters and crossover frequency filter. These can be used to "shape" the sound and enhance the desired effect.
Equalization
The XTi2 Series provides two blocks of equalization in the signal processing. The input EQ block is before the
crossover and is usually used for the room EQ. The output EQ block is after the crossover and is usually used
for speaking tuning.
Input EQ: This input EQ block provides 6 filters per channel each with frequency, gain, and Q that is user
controllable. This block also has a High and Low Shelf Filter per channel which has gain and frequency
control.
Output EQ: This output EQ block provides 8 filters per channel each with frequency, gain, and Q control that is
user controllable.
Crossover:
The crossover section provides users with the ability to enable a HighPass and LowPass filter per channel
along with BandPass gain and the ability to change the polarity. This allows the Crossover section to be
customized to most system configurations.
For the HighPass and LowPass Filters, you have the choice of the following filters: Butterworth 6dB/oct,
Butterworth 12dB/oct, Butterworth 18dB/oct, Butterworth 24dB/oct, Butterworth 48dB/oct, Linkwitz-Riley 24dB/
oct, and Linkwitz-Riley 48dB/oct.
The BandPass gain provides you with -15dB to +15dB of gain.
